I bought a pellet stove from Ehrhart and it keeps going out when the wind blows hard. I then bought over $300 worth of vent pipe and it still goes out. I then read the installation instructions to find out it was the wrong length so it was not installed correctly to begin with and after the new pipe was put on so i am out all that money and I have to pray the wind doesn't blow all winter, like that will happen. I can go on but I won't.
